6 Speed ZF UK Class 172 with kickdown to 100mph

[@wrightrenowns448kcw7]

These things are so good, probably my favourite ever DMUs

[@statusquorules]

In the 2 speed 170, once the train gets up to around 60 it switches into direct drive rather than the torque converter so the engine revs drop quite dramatically and its quieter

[@duncanbhaltaireanraigwilso9627]

It's 70mph for the 170.

[@OdhranMurray]

Simulatorguy101 our school bus does, although the 170's sound better

[@joshuahalla.k.a.controlla6333]

I was thinking the same thing, I wish that their was a bus that had the same gearbox and engine as the class 172's.☺️

[@armanicrompton787]

Well, a Volvo B7RLE’ Euro 4 sounds similar to them when at speed tbh.

[@SPTSuperSprinter156]

Oh my, this takes me back to Denmark, when I rode their IC 3 rubber nose DMU from Hamburg to Copenhagen. Though I'm lead to believe those use a 12 speed ZF and they simply skip a gear every time they shift up, so it sounds like a 6 speed. Trains that sound like this are awesome, way better than the 2-speed sound of other DMUs like 156.

[@ThiagoMarquardt]

They use zf eco life rail 6 speed with torque converter. But I think a good amt with 12 or 16 speed as zf MAXON could be even better.

For those who don't know.ghe electrostar and turbostar series of old use and older styles bogie . Which is heavier. These newer 172s use lighter newer bogies similar to those seen on aventras. Meaning the total weight of the unit could be over ten tons less., enabling better acceleration overall

[@RonnDon]

I never knew trains used ZF and Voith!

[@poopsymcloopsy]

i will always follow you

[@ChrisRichmond]

ronnoc1k8 Trains have used ZF and Voith for many years. The original Sprinters/Turbostars/Chiltern Turbos all have the Voith T211r transmission and the Class 170s were fitted with the ZF final drive. Before these second generation DMUs, the old railcars used epicyclic gearboxes (yes- 'boxes with actual gears like on a bus!) that were changed manually, but later became self-changing as they were developed into those originally fitted to the Class 14x Pacers. The Pacers have since had their original powertrain removed and were all re-fitted with the Cummins/Voith powertrain like a Sprinter unit. However, it seems slightly "backward" that Bombadier have reverted back to using a gearbox designed for buses in a railway vehicle! Let's hope that in a few years time, the gearchanges are smoother than they are on their road-going bus "cousins"...

[@gtatransit_cinematography]

Then the technology went all over the world, even in Canada in it's capital. Ottawa's OC Transpo Trillium Line

[@CreightonRabs]

Voith appears to be the more common of the two when it comes to DMUs. I didn't know until I found out on Wikipedia that ZF made transmissions for DMU. Definitely prefer this sound to the Voiths, to be honest.

[@jack253]

Sounds more of Abellios Enviro 400 when changing gears.

[@TheFlatCapFromWN5]

The government were (once upon a time) on about replacing the dreadful pacers that Northern Rail use with these. But then they had to change their mind so now I have to endure five more years of the pacers. Damn it.

[@milkandduckrailway323]

@@grangergranger6965 Same engine and gearbox but more insulation to make it more quieter.

[@kinkymudic]

those are great ZF gearbox sounds in the class 172 please look at the london midland class 172 #

[@MrAndybye]

Why don't more diesel trains have the ZF? It must be more economical with the engine not having to rev up to get moving & better acceleration through the gears. Also it's less boring than the constant drone of an engine at the same revs irrespective of speed.

[@TheFlatCapFromWN5]

I believe the new Class 195 units that will be entering service with Northern will use epicyclic ZF gearboxes so that's something to look forward to.

[@StephenKHLee]

A sound mixture of a Dennis Dragon/Condor w/ Cummins L10 Engine, Volvo Olympian with a Volvo TD102KF/D10A Engine.

[@thebrummierailenthusiasts5329]

It’s almost sounding like a double decker bus when changing gears automatically when powering up or slowing down

[@duncanlaverty1423]

Quite a strange but interesting sounding machine, hope they end up here in Yorkshire while i draw breath, but I doubt it somehow lol

[@britishfilmguy]

Nice to see the class 195 and class 196 using what I believe is a zf gear box to be fair nice to see Trains using a auto matic gear box makes the sound of a diesel engine off a hgv stuck in neutral alot better.

[@StephenKHLee]

Very lovely sound, it’s me as a school choir boy’s favorite

[@Andrewjg_89]

The Northern Class 195 Civity probably has the same kind of engine as on the Class 172. Which CAF have manufactured the Class 195 and Bombardier who manufactured the Class 172.

[@orlestone]

Pretty much. They're both MTU6H1800 power units, but the ones on the class 195 are 390KW (530 bhp), compared to 360KW (483bhp) in the class 172. The 195's also have the ZF 6 speed box, and sound just like this. As a point of order, having spent a lot of time on 195's and listened to this video several times, I don't hear any "kickdown" (which implies changing to a LOWER gear in order to accelerate). All I hear is the train working through the gears as you would expect it to. Sounds interesting though. The acceleration on the 195's in 2nd gear is phenomenal!

[@Andrewjg_89]

⁠Sounds about right. Not forgetting the West Midlands Railway Class 196 and Transport for Wales Class 197.

[@Housephonestimes4]

Just like a Class 110 dmu! Love it!😊

[@MoeJae86]

I'm new to these units and I've never heard a train shift like automobile before. So do these units have a diesel to mechanical transmission? Rather than the diesel electric setup?

[@fetchstixRHD]

Yeah, these units are diesel mechanical I believe. Actually very few Diesel Multiple Units over here are Diesel Electric

[@ChangesOneTim]

The 172s are not fitted with tripcock train protection, so that they cannot legally operate over LUL lines.

[@liamcbs]

i think thats the only 172 class to have kickdown?

[@camelcamel6816]

I can only count 5 speeds. Is anyone mix up with the gear 2 hydraulic as one separate gear? The gearbox went through all gear 1 hydraulic, gear 1 mechanic, gear 2 hydraulic and gear 2 mechanic under the full power mode.

[@KickdownLondon]

Hi, I've updated the description with the times it changes into each gear. The torque converter is part of the 1st gear, at 0:23 you can hear it subtly exit the torque converter stage.

[@michelesilla]

@@KickdownLondon i also think that this is clearly a 5 speed and not a 6 speed. the 4-5 shift on an Ecomat sounds like a 5-6 shift on an ecolife, because the gear ratios of 4 and 5 on an ecomat are closer than for example a 3-4, the same on the 5-6 on an ecolife. so when you say it shifts to 6th, in reality it shifts to 5. i think you also know that the shift from 5 to 6th in an ecomat drops the rpms very very much, which wouldn't be very intelligent in this application. i so think that the shift pattern is as follows: 0:12 - 1 gear unlocked (preparing to lock at low-ish rpms) 0:33 - 1 gear locked (now bringing the rpms very high) 0:42 - 2 gear unlocked (first rpm drop, ready to immediatly lock at low-ish rpms) 0:43 - 2 gear locked (second small rpm drop, now shifting at hight rpms again) 1:01 - 3 gear (41% drop, 2.01(2nd) to 1.42(3rd) gear ratio) 1:24 - 4 gear (42% drop 1.42(3rd) to 1.00(4th) gear ratio) 2:04 - 5 gear (20% drop 1.00(4th) to 0.83(5th) gear ratio) also, an ecomat doesn't usually bring the rpms very high when in the torque converter stage (to help reduce waste in the tc), and this explains why at 0:33 and 0:43 it "shifts" quite early compared to all the other gears. a shift from 5 to 6th would mean changing the ratio from 0.83 to 0.59, which is a drop of again 40% and you can clearly hear that this doesn't happen

[@michelesilla]

@@KickdownLondon also, at 0:25 you can clearly hear that the rpms are immediatly rising but the speed remains the same, this wouldn't obviously happen in a locked stage, so the torque converter isn't yet locked and is allowing the engine to enter the power curve before locking

[@liamcbs]

is that the london marylebone service?

[@renownlover5156]

What section of line is this?

[@BabyRosalinaFan82]

I'm very lost. This sounds just like an average turbostar, am I right? I've never heard a turbostar change gears before, if so, maybe one shift - if what I'm thinking of is even a shift. What's the difference between this and, say, a modern GWR Class 166?

[@RWL2012]

only 172s (and 195/196/197s) have 6-speed gearboxes like this - most other DMUs (including 166s) have hydraulic transmission (hence the one shift on a 2-stage hydraulic) with the rest having electric transmission, so they don't have frequent "bus-style" gear changes like this.

[@BabyRosalinaFan82]

A long time now - the old pacers and slam door diesels sounded a lot like Routemasters/RTs, ZFs aren't that common in modern DMUs however. The Class 172s and one Class 158 have ZFs, whilst Class 180 and 185s have a 3 speed Voith transmission.
